You can use the DocumentBuilder#addTag option when setting up Swagger to document the tag:

new DocumentBuilder()
  .addTag('auth', 'Auth endpoints description')
  .build();

There is no option available afaik to add a description at the controller level. You can only add one or more tags at the controller level with @ApiTags.
